 But if we ever make regular directory activity multihop, this could apply
 there too. Plus the linked conn close conditions may be relevant to this
 bug?

 In some cases, bridge clients fetch authority certificates over multihop
 connections:
 https://github.com/torproject/tor/blob/94605f08fb89ea79409225362d2fa0f8a07435d7/src/feature/nodelist/routerlist.c#L952

 And do most other actions over multihop connections:

 And bridge relays upload descriptors over multihop connections:
 https://github.com/torproject/tor/blob/48632455a5bd679d5f97c5137f24f91e564abad6/src/feature/dircache/directory.c#L379
